FIELD: mining. ^ SUBSTANCE: installation consists of depression chamber with hollow piston hydraulically connected with successively downright installed device of hydro-dynamic effect made in form of a diffuser-confuser and elastic ball, with slime-receiving chamber and with shut-off device made in form of gate valve, with receiving branch and with valve. The receiving chamber for the elastic ball is formed at the section between the hollow piston and the diffuser. A container with recording equipment is located between the slime-receiving chamber and the gate valve. The hollow piston is designed to be secured on a flow string. The receiving branch is made in form of a feather with radial holes on side surface. The valve is of a dump circulating type and is assembled on side surface of the depression chamber. ^ EFFECT: simplified design, increased efficiency of cleaning, facilitating ecological safety. ^ 2 dwg |
